• Question 126:

  Which action occurs during a Layer 3 roam?

  A. The client receives a new IP adcress after authentication occurs.
  B. The client is marked as `'foreign" on the original controller.
  C. The client database entry is moved from the old controller to the new controller.
  D. Client traffic is tunneled back to the original control after a Layer 3 roam occurs.
  C. The client database entry is moved from the old controller to the new controller.

• Question 127:

  Which feature does the Cisco DNA Center User-Defined Network workflow provide?

  A. Automatic segmentation of IoT devices
  B. Replacement of malfunctioning devices
  C. Automatic provisioning of AP devices
  D. Interface for AP configuration
  A. Automatic segmentation of IoT devices

  ---

  Explanation

  The correct answer is Option A. Automatic segmentation of IoT devices.

  Cisco DNA Center User-Defined Network provides a workflow for segmenting user and IoT devices into isolated network groups. This is useful in environments where many personal or IoT devices need secure access without being placed into the same shared network segment.

  Option B is incorrect because the workflow does not replace malfunctioning devices.

  Option C is incorrect because AP provisioning is a separate wireless deployment function.

  Option D is incorrect because the feature is not primarily an AP configuration interface.

• Question 128:

  

  Refer to the exhibit.

  Which HTTP request produced the REST API response that was returned by the Cisco Catalyst Center (formerly DNA Center) platform?

  A. POST /auth/token
  B. GET /network-device
  C. GET /template-programmer/template/version/42a3df73-3ef4-49e2-b4f0-6927bbd4bf52
  D. POST /discovery
  B. GET /network-device

• Question 129:

  Refer to the Exhibit.

  

  An engineer is installing a new pair of routers in a redundant configuration. When checking on the standby status of each router the engineer notices that the routers are not functioning as expected.

  Which action will resolve the configuration error?

  A. configure matching hold and delay timers
  B. configure matching key-strings
  C. configure matching priority values
  D. configure unique virtual IP addresses
  D. configure unique virtual IP addresses

  ---

  Explanation

  The most situable for this question is D (configure unique virtual address) as is one of requirements for a group to work, as seeing in the image. The others are wrong for the following reason. (so Wrong based in the question) A) Not mandatory the timers must match to work on HSRP. on HSRP negotiation the active router will override the standby timers.

  https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9000/nb-06-cat-9k-stack-wp-cte-en.pdf

  B. On the image key string match so is not this reason HSRP cant be seen each other

  C. Wrong, priority is for selecing the active router, the best practice is should be different thus (WRONG)

  D. Different virtual Gateway configured on the same group number indeed will make HSRP routers negotiation fail for that group thus (CORRECT)

• Question 130:

  What is one difference between EIGRP and OSPF?

  A. OSPF is a Cisco proprietary protocol, and EIGRP is an IETF open standard protocol.
  B. OSPF uses the DUAL distance vector algorithm, and EIGRP uses the Dijkstra link-state algorithm
  C. EIGRP uses the variance command lot unequal cost load balancing, and OSPF supports unequal cost balancing by default.
  D. EIGRP uses the DUAL distance vector algorithm, and OSPF uses the Dijkstra link-state algorithm
  D. EIGRP uses the DUAL distance vector algorithm, and OSPF uses the Dijkstra link-state algorithm

  ---

  Explanation

  EIGRP is based on DUAL (Diffusing Update Algorithm) while OSPF uses Dijkstra's Shortest Path Algorithm with the major difference in how they calculate the shortest routing path. OSPF has capability to calculate the best shortest path to each reachable subnet/network using an algorithm called SFP (Shortest Path First) also known as Dijkstra algorithm. "Neighbor Table" that contain all discovered OSPF neighbour with whom routing information will be interchanged.
